Used as a key chiral building block in the synthesis of pharmaceuticals, particularly in the development of protease inhibitors and other bioactive molecules. Its rigid bicyclic structure and defined stereochemistry make it valuable for constructing stereoselective drug candidates. Commonly employed in medicinal chemistry for structure-activity relationship (SAR) studies, especially in optimizing potency and metabolic stability. The Boc-protected amine and carboxylic acid functionalities allow for straightforward incorporation into peptide-like frameworks and further derivatization in multi-step syntheses.
